Answers and Solutions

(1-5) :

(3) No. of qualified candidates in the year 2005 = 900 × 64100 = 576

No. of male candidates who qualified in the year 2005 = 576 – 176 = 400

Required ratio = 400 : 176

= 25 : 11

(4) No. of qualified candidates in the year 2006

= 700 × 140100 × 25100 = 245

(3) Let the appeared candidates in the year 2002 = 500 and qualified candidates in the year 2002 = 400

No. of qualified female candidate = (4008 3 ) = 150

Required% = (150500 100) % = 30%

(4) No. of qualified candidates in the year 2004 = 724 14 = 252

Total no. of appeared candidates in the year 2004 = (25242 100)% = 600
